It is a street car, the 408 make 550 horse with 560 pound feet torque. It is just my rod and I take it to shows and the grandkid for rides. I had a idea of the answer but wanted a newer prospective of what is going on today. Sometimes you can be on the edge and a little over has a different outcome. My bother and I had a Division 5 Pro Stock (other brand) Camaro in the late 70's and early 80's. The only engine work I have done is this Dart and the Pantera's I work on. 90 % are high performance street cars, so nothing too exotic.
